What is the "Simple MAPI" ?
Simple MAPI is a subset of 12 functions, which enable developers to add basic messaging functionality to their Windows-based applications.
It includes functions to support sending and receiving messages:
|•||Log onto the messaging system.|
|•||Compose new messages, add and resolve recipients, send messages.|
|•||Retrieve and read messages from the inbox.|
The Simple MAPI functions can be called from any application that supports both making API calls as well as the structures and data-types used by Simple MAPI, such as C, C++, Visual Basic, and Visual Basic for Applications (VBA).
"The MAPI controls included with Microsoft Visual Basic (versions 3 through 6), and the version of MAPI installed by Outlook Express implement Simple MAPI only."
